Hi,
I spent some time looking into how to find tau (time constant) of this circuit shown in the professor's handwritten problem and couldn't fully grasp whether he made a mistake or I had. Could some be so kind to help me out with the problem.
Here's the problem copied and worked out by me.
Here's my professors work. The problem is the one underneath the line.
My concern is that the time constants don't match up. I have tau = 4/9 and he has it = 2/9. Which is right?
My guess is that I didn't make any mistakes and he copied the time constant form the problem above the line by accident into the problem below the line.
